fix(docs): use window.execScript instead of window.eval on IE

IgorMinar · IgorMinar · commit 2d489ff93639 · 2011-09-06T14:58:39.000-07:00
IE's window.eval doesn't execute in the global context, so we have to
use window.execScript instead which works like window.eval on normal
browsers. However execScript throws an exception when an empty string is
passed in, so I created a workaround with a workaround.
